AvNav Timer 作者： Raina T

AvNav Timer is a lightweight time-tracking extension built for AvNav users (and adaptable to any site) who need an accurate, low-effort record of hours worked.

What it does:

Automatic time tracking — detects which open tab has focus and logs time against configurable "work," "other," and "excluded" domains, so you don't have to start/stop a timer manually.
Activity measurement — samples mouse, keyboard, and scroll input per segment to estimate how actively you were engaged, not just which tab was open.
Idle detection — pauses tracking automatically when your system goes idle, so idle time doesn't inflate your hours.
Periodic screenshots — optionally captures the active tab at a configurable interval as a lightweight work log/proof of activity.
Earnings & reports — set an hourly rate and generate daily, weekly, monthly, or custom-range PDF reports summarizing time worked and earnings.
Session overlay — an optional on-page indicator shows whether the current tab is being tracked.
Privacy: All tracking data, screenshots, and settings are stored locally in the browser via storage.local. Nothing is ever transmitted to a remote server — the extension has no backend and collects no data on you.

Permissions used:

storage — save settings, time logs, and stats locally
alarms — schedule periodic heartbeat/screenshot checks
idle — detect system idle state to pause tracking
tabs — identify the active tab's domain for categorization
downloads — save generated PDF reports to disk
Host access — needed to track time across the sites you configure and to inject the optional tracking overlay
